[0003] Among the types of measuring rulers, the engineering supervision measuring ruler is a commonly used measuring instrument in construction projects. The engineering supervision measuring ruler is an engineering inspection tool. The main function of the engineering supervision measuring ruler is to check whether the building object is in the correct position and whether it has met the design requirements.

[0004] Some existing engineering supervision measuring rulers are usually only able to achieve single angle measurement or length measurement due to their single functionality, and cannot meet the diverse measurement needs in construction engineering supervision. In addition, the inspection device cannot be effectively stored, which causes inconvenience during carrying and transportation. When it is necessary to measure the surface flatness of an object, etc., the staff needs to frequently change different measuring tools, which increases the complexity of the operation. At the same time, the length of the existing tools is limited by the manufacturing process, so that when measuring a larger area, the staff needs to constantly move the measuring ruler, which not only reduces the measurement accuracy, but also affects work efficiency. To this end, in response to the above problems, a new type of supervision measuring ruler for engineering supervision is proposed to solve the above problems. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Reference Figures 1 to 3 The present invention provides an embodiment of a novel supervisory measuring ruler for project supervision, comprising a measuring ruler 1. The middle portion of the measuring ruler 1 is formed by a long cross-shaped slot, with scales and through-holes on either side. The scales facilitate reading data, while the through-holes facilitate drawing lines. Two foldable auxiliary rulers 2 are rotatably connected to the right side of the measuring ruler 1. One of the foldable auxiliary rulers 2 engages with the top of the measuring ruler 1 without obstructing the scale lines of the measuring ruler 1, and the other engages with the middle portion of the measuring ruler 1.

[0036] To the right of the top folding ruler 2 is an angle measuring instrument 3. This instrument incorporates advanced electronic sensor technology, enabling precise angle measurement. A digital display allows for direct reading of angle values, offering high accuracy and convenient reading. The ends of the two folding rulers 2, facing away from the angle measuring instrument 3, are pivotally connected to a slider 4. This slider 4 deflects the ends of the two folding rulers 2 away from the angle measuring instrument 3, while the other ends of the two folding rulers 2 are fixed to the left end of the measuring ruler 1.

[0037] refer to Figure 4 、 Figure 5 A push button 5 is slidably connected to the center of the two sliders 4. The user can lock the angle by pressing this button 5, which is crucial for ensuring measurement accuracy. A heart-shaped slot 6 is defined on the front of the push button 5. This unique shape, combined with a Z-shaped latch 7, allows the push button 5 to be fixed at a specific point, thereby locking the desired measurement angle. The Z-shaped latch 7 is rotatably connected to the front of the slider 4, with its top end pivoting to the bottom of the inner wall of the slider 4.

[0038] The top end of the Z-shaped card rod 7 is slidably connected to the inner wall of the heart-shaped card slot 6, and the heart-shaped card slot 6 can accommodate and guide the Z-shaped card rod 7 to slide along its path. When the button 5 is pressed, the Z-shaped card rod 7 is driven to slide along the card slot and finally engages with the top tip of the heart-shaped card slot 6. The bottom end of the button 5 is fixedly connected to a connecting roller 8, and the outer sleeve of the connecting roller 8 is provided with a spring 9. The connecting roller 8 not only serves as a mechanical connection device, but also has a spring 9, which plays a role in compression and providing rebound. The top end of the spring 9 is fixedly connected to the bottom end of the button 5, and the bottom end of the spring 9 is fixedly connected to the inner wall of the slider 4. The spring 9 drives the button 5 to reset.

[0039] The outer portion of the slider 4 is slidably connected to the middle inner wall of the measuring ruler 1. The bottom end of the connecting roller 8 is fixedly connected to a conical clamping block 10. The outer top end of the conical clamping block 10 is engaged with the middle inner wall of the measuring ruler 1. When the Z-shaped clamping rod 7 pushes the pressing block 5 downward, the conical clamping block 10 is driven up and engaged with the inner wall of the measuring ruler 1, ensuring that the measuring ruler 1 does not move during the angle measurement process.

[0040] refer to Figure 6 、 Figure 7The left end of the measuring ruler 1 is fixedly connected to a straightedge 11, and a straightedge 2 12 is slidably connected to the interior of the straightedge 11. The functions of the straightedge 11 and the straightedge 2 12 are used to measure flatness. A gear 13 is rotatably connected to the middle of the rear end of the straightedge 2 12. A rack 14 is fixedly connected to the interior of the straightedge 11. The external teeth of the gear 13 mesh with the external teeth of the rack 14. The gear 13 meshes with the rack 14 inside the straightedge 11, forming a stable sliding mechanism. The upper and lower sides of the rack 14 are slidably connected to the middle of the straightedge 2 12. By sliding the upper and lower sides of the rack 14 against the interior of the straightedge 2 12, the straightedge 2 12 can slide out stably.

[0041] A limit assembly is installed on the rear side of the second straight ruler 12. The limit assembly includes two limit slots 15, located on the inner wall of the rear side of the second straight ruler 12, and located above and below the gear 13. Two limit rollers 16 are fixedly connected to the inner rear side of the first straight ruler 11. These limit rollers 16 are equipped with limit heads located away from the first straight ruler 11. The outer portions of the limit slots 15 are slidably connected to the inner walls of the limit rollers 16, cooperating with the gear 13 and rack 14 to limit the sliding distance of the second straight ruler 12.

[0042] A bubble level 17 is fixedly attached to the front of the top of the second straight ruler 12, and two bubble levels 18 are fixedly attached to the top of the first straight ruler 11. Both the first straight ruler 11 and the second straight ruler 12 are equipped with the first bubble level 17 and the second bubble level 18. The built-in bubbles and scale lines of the first bubble level 17 and the second bubble level 18 can help users monitor the flatness of the object being measured in real time.

[0043] Working principle: When in use, the user can use the measuring ruler 1 to measure the wall or the object to be measured. Secondly, when it is necessary to measure the angle, the slider 4 can be pushed to allow the slider 4 to drive the foldable auxiliary ruler 2 folded on the measuring ruler 1 to unfold with the measuring ruler 1 as the center, and the foldable auxiliary ruler 2 on one side can be attached to the end to be measured. The foldable auxiliary ruler 2 at the other end can be continuously moved by the slider 4, and finally the two sides of the foldable auxiliary rulers 2 can be attached to the measured object. Then, the angle measuring instrument 3 is used to monitor the unfolded angle of the two foldable auxiliary rulers 2 to obtain the angle data of the measured object.

[0044] When the foldable auxiliary ruler 2 is unfolded to fit the object being measured, the user can press the button 5, which drives the Z-shaped clamping rod 7 through the heart-shaped clamping groove 6 to slide along the outer groove of the heart-shaped clamping groove 6 until it engages with the tip of the heart-shaped clamping groove 6. Simultaneously, when the Z-shaped clamping rod 7 engages with the top of the heart-shaped clamping groove 6, the button 5 pulls the tapered clamping block 10 upward via the connecting roller 8, allowing the tapered clamping block 10 to slide inwardly with the middle of the measuring ruler 1 using its outer tapered shape, thereby fixing the angle measured by the foldable auxiliary ruler 2 and ensuring the accuracy of the data monitored by the angle measuring instrument 3. After pressing the button 5 again, the Z-shaped clamping rod 7 slides back along the other side of the heart-shaped clamping groove 6, unlocking the tapered clamping block 10.

[0045] When the user needs to measure the flatness of the object being measured, the user pulls the second level 12 and slides it inside the first level 11, allowing the gear 13 fixed to the rear side of the first level 11 to engage with the teeth of the rack 14 of the second level 12 to ensure that the first level 11 does not shake after being pulled out. When the second level 12 is extended and retracted to the appropriate position, the user can monitor the flatness of the object being measured by observing the bubble level 2 18 of the first level 11 and the bubble level 17 of the second level 12.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
